Some of the key features of SIR v3.0.1 include the following:


Support of different input data formats : SIR v3.0.1 can import different data formats such as text (*.rtf, *.doc, *.txt), spreadsheet (Excel, Quattro Pro) and database formats (Paradox, Access, Oracle...). A minimum amount of information is needed to conduct an SIR analysis (i.e. product type, date, closing dip volume (stick), gross deliveries, daily sales in 28 days of observation). SIR v3.0.1 allows each client to have its own import template. (example of Excel format shown in Figure 1f.)

 

Fully Automated Import Routine (Figure 2f.): For ongoing leak detection, fuel inventory accounting data are uploaded on a daily basis. The import routine can easily be customized to suit any client needs. During the data import  process an automated qualitative leak check is performed on each tank system to provide early detection of moderate to large leaks (daily flags routine Figure 3f.). In addition, an automated refined quantitative analysis (automated SIR run Figure 4f.), and subsequent manual review, are performed on a subset of the sites. The subset is changed each day so that each tank system is eventually subjected to a refined quantitative analysis over the coarse of a month. The process is then repeated each following month.
The daily flags routine is not expected to provide reliable detection of small (chronic) leaks, and therefore, is not a replacement for the detailed monthly SIR analyses.


User friendly interface: SIR v3.0.1 features a professionally designed user interface. (Figure 5f displays SIR Automate/Analysis menu)



Graphical representation of input data: SIR v3.0.1 displays input data graphically. The SIR operator to visually spot site activities and changes in trends. Different symbols are used to readily distinguish between non-receipt, receipt (delivery), adjustment, and rejected days. Inventory data for a specific day may be viewed by clicking on the point on the graph. A pop-up tabular summary of the inventory data then appears (Figure 6f. shows daily and cumulative reconciliation error graphs while Figure 7f. shows inventory data for clicked point)



Dip Chart Calibrations: An approximate correction can be made for tank-length errors where dips are provided in units of volume. However, to perform a proper dip-chart calibration which considers all types of dimensional and geometry errors, it is necessary for dip readings to be provided in units of length. Also, it is necessary to know the general geometry of the tank, namely: the type of tank body (i.e., cylindrical tube, tapered tube, or two tapered sections joined together), the type of end caps (i.e., flat, dished, ellipsoidal or hemispherical), and if the tank is compartmentalized. The more information that is known about the tank, the easier it is to backcalculate the true dip chart. The program may also scan a library of known dip charts to find the best match (Example of dip chart calibration screen shown in Figure 8f.)



Graphical Output: SIR v3.0.1 provides presentation-quality graphs that show monthly and annual trends in cumulative reconciliations errors. The detailed Results screen (Figure 9f.) presents the summary of the results from the tightness test including the recommended actions to be taken by the tank owner/operator (Figure 10f. shows annual cumulative graph).



Clear and concise reports: The completed reconciliation reports (Inventory records, Detailed SIR Results and Site Summary)  may be viewed on the computer's monitor and copies of the reports may be printed at the press of a button (click here to see Site Summary Report displayed in Figure 11f.).
